The pregnant star posted a split image of her Cannes outfit from the front and behind with a lyric from 'Baby Got Back' as the caption. Cue outrage on Twitter.

Blake Lively has been accused of racism and being “white and privileged” after she posted a controversial caption on Instagram about her body.

The 28 year old star, who is pregnant with her second child with husband Ryan Reynolds, posted a split picture of images taken from the front and back when she was at the premiere of her new movie Café Society at Cannes last week, captioning it “L.A. face with an Oakland booty”.

Quickly, the actress came under fire from commenters who accused her of being privileged, using black women and culture as a “punchline”.

Never mind that Lively was simply quoting a lyric from Sir Mix-A-Lot’s 1992 hit ‘Baby Got Back’, which contrasts Oakland (a predominantly black area of California) with Los Angeles, or that Katy Perry and Khloe Kardashian have recently used the same phrase to caption their own selfies without triggering such bile - Twitter was on her like a ton of bricks.

As of the time of writing, Lively has not offered any apology for the comment, and neither has she taken it down from Instagram.

Meanwhile, she has been wowing many with her choices of clothing as she steps out on the red carpet promoting Café Society, the latest movie by Woody Allen. A great many commented on the Versace dress she wore last week in Cannes, proving that high fashion and maternity outfits can go together.
